Avoids an excessive DOM size - 144 elements
Browser engineers recommend pages contain fewer than ~1,500 DOM elements. The sweet spot is a tree depth < 32 elements and fewer than 60 children/parent element. A large DOM can increase memory usage, cause longer [style calculations](https://developers.google.com/web/fundamentals/performance/rendering/reduce-the-scope-and-complexity-of-style-calculations), and produce costly [layout reflows](https://developers.google.com/speed/articles/reflow).

Network Round Trip Times - 0 ms
Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance. Learn more.

Preconnect to required origins
Consider adding preconnect or dns-prefetch resource hints to establish early connections to important third-party origins. Learn more.

Minify CSS
Minifying CSS files can reduce network payload sizes. Learn more.

Server Backend Latencies - 0 ms
Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance. Learn more.

Defer offscreen images
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn more.

Properly size images
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.

Serve images in next-gen formats
Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. Learn more.

Minimize Critical Requests Depth - 8 chains found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load. Learn more.

Preload key requests
Consider using to prioritize fetching resources that are currently requested later in page load. Learn more.

Minify JavaScript
Minifying JavaScript files can reduce payload sizes and script parse time. Learn more.

Use video formats for animated content
Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes. Learn more.

Server response times are low (TTFB) - Root document took 150 ms
Time To First Byte identifies the time at which your server sends a response. Learn more.

Efficiently encode images
Optimized images load faster and consume less cellular data. Learn more.

Enable text compression
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more.

Avoids an excessive DOM size - 144 elements
Browser engineers recommend pages contain fewer than ~1,500 DOM elements. The sweet spot is a tree depth < 32 elements and fewer than 60 children/parent element. A large DOM can increase memory usage, cause longer [style calculations](https://developers.google.com/web/fundamentals/performance/rendering/reduce-the-scope-and-complexity-of-style-calculations), and produce costly [layout reflows](https://developers.google.com/speed/articles/reflow).

Use video formats for animated content
Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes. Learn more.

Server response times are low (TTFB) - Root document took 170 ms
Time To First Byte identifies the time at which your server sends a response. Learn more.

Enable text compression
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more.

Efficiently encode images
Optimized images load faster and consume less cellular data. Learn more.

Network Round Trip Times - 0 ms
Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance. Learn more.

Preconnect to required origins
Consider adding preconnect or dns-prefetch resource hints to establish early connections to important third-party origins. Learn more.

Minify CSS
Minifying CSS files can reduce network payload sizes. Learn more.

Server Backend Latencies - 0 ms
Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance. Learn more.

Properly size images
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.

Serve images in next-gen formats
Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. Learn more.

Minimize Critical Requests Depth - 9 chains found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load. Learn more.

Suggestions Summary

Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 1 blocking script resources and 1 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.Remove render-blocking JavaScript:

Avoid landing page redirects

Your page has 2 redirects. Redirects introduce additional delays before the page can be loaded.

Avoid landing page redirects for the following chain of redirected URLs.

http://academia.edu/
http://www.academia.edu/
https://www.academia.edu/

Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Leverage browser caching for the following cacheable resources:

https://connect.facebook.net/en_US/sdk.js (20 minutes)
https://apis.google.com/js/api:client.js?onload=loadGoogle (30 minutes)
https://accounts.google.com/o/oauth2/iframerpc?action=checkOrigin&origin=https%3A%2F%2Fwww.academia.edu&client_id=331998490334-rsn3chp12mbkiqhl6e7lu2q0mlbu0f1b (60 minutes)
https://www.google-***ytics.com/***ytics.js (2 hours)

Minify JavaScript

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and *** time.

Minify JavaScript for the following resources to reduce their size by 671B (39% reduction).

Minifying https://connect.facebook.net/en_US/sdk.js could save 671B (39% reduction) after compression.
